Name of the Vulnerable Software and Affected Versions Android for MSM (affected versions not specified) Firefox OS for MSM (affected versions not specified) QRD Android (affected versions not specified)

Recommendations For Android for MSM, consider applying configuration changes to the mobicore driver to validate the length field for memory allocation. For Firefox OS for MSM, restrict access to the mobicore driver until a proper fix is applied. For QRD Android, as a temporary workaround, consider disabling the mobicore driver to prevent potential kernel memory overwrites.
